Actualy, if you listen carefuly to what he's saying, he's saying that the concept of a supernatural "creationism" is bogus, and that is based on the multiverse concept rather than the simulation concept. And saying "Supreme Being" does not neccessarily indicate a "God" being. A race that has existed for billions of years longer than our own would defenatly seem to us to be a race of supreme beings. This is not to say that they are gods. They may have created our universe in a simulation, but that doesn't mean they are God. Unless you liken us to ants in an ant farm worshipping its 12 year old "keeper" as a God.
